Interest in farming seaweed for carbon removal is ramping up. We collaborated with a research team to build an interactive tool for mapping seaweed farming potential, and wrote an explainer summarizing the results.

There's growing interest in methods to value temporary carbon storage. In two recent pieces, we explain a practice called ton-year accounting, and raise concerns about how it's being used in practice.

We analyzed the flow of carbon offset credits from conventional registries to the blockchain. Our work shows that nearly all of these credits have been excluded from conventional markets.

Should policymakers track net greenhouse gas emissions across the energy and lands sectors, and if so, how? We explored the complex choices required to account for forests and power plants in the same emissions inventory.

Ton-year accounting is used to quantify the value of temporary carbon storage — a task for which we lack a clear intellectual framework. We explain how ton-year accounting methods work and highlight crucial differences between prominent ton-year accounting methods.

Policy Brief
California’s net-zero climate plan is long on carbon removal, short on details, and based on flawed analysis.

Policy Brief
Voluntary carbon markets don't provide investors with adequate data about who is using offset credits, nor what kinds of climate claims those credits justify. Simple disclosures would fix this gap.

We review concerns with NCX’s use of discounted ton-year accounting methods to credit short-term timber harvests delays.

The Journal of Ocean Technology
A short article outlining the challenges of incorporating ocean-based CDR into carbon markets and the need for those who know the science to track claims carefully and help others do the same.
